5. Maintenance of the We.R
™
System
The We.R
™
system is almost maintenance-free; the only maintenance-oriented activities
required for its continuous operation are:
1. Replacing Batteries – an indication of the need for batteries replacement is provided by
both the We.R
™
Web Application and the We.R
™
Mobile Application utilizing their different
status displays.
2. Cleaning the Smoke Detector’s filter – on a monthly basis, to remove dust that might block
the path to the sensor.
Other than that, there is no other maintenance activity required for proper operation of the
We.R
™
system.
